Elint in Lamina, Application of a Object Language

Abstract: The design and performance of an "expert system" signal interpretation application written in a concurrent object-based programming language, LAMINA, is described together with a synopsis of the programming model that forms the foundation of the language. The effects of load balancing and the limits imposed by task granularity and message transmission costs are studied and their consequences to application performance are measured over the range of one to 250 processors as simulated in SIMPLE/CARE, an extensively instrumented simulation system and computer array model.
